When you go to p/u the machine take along 30 feet of rope.
If you are not given the rider's manual, the fork and shock manuals and the tool kit complete with the KTM bottle opener...show the salesman the rope that you are authorized to hang him with or offer to weave a rope from his own hair to accomplish the same.

The rider's manual gives specific instruction on adjusting the chain as well as measuring it for wear.
